ignition systems
#4
i can't really help either. currently have jacobs ignition amp and TII coils but it wasn't wired right so my trailings aren't firing. as soon as i can save up enough cash i want to run dual msd amps with 4 coils. that would be more than enough to handle your 500 too i believe

^ What he said
I run the stock 13B-REW set up with HKS DLI and new NGK plug leads, water injected 20+psi boost, more power than your gearbox or rear tires can handle !
I have trialed all types of ignition including my own coil on plug CDI set up, the stock ign when in good order and small upgrades as listed above is fine.
Greddy 10 or colder plugs is what I have always recommended and many around the world have copied/followed suit after I started using them wholesale 5 years ago.
